摘要： An apparatus and method for use in testing devices under high-g environments is disclosed in which an elastic beam, rigidly fastened at least at one end, carries the device under test; the beam being pre-loaded to a bent position by a force producing member which may be suddenly removed to allow the stored energy of the beam to be released, and to apply a high-g force to the device.

摘要： The present invention provides systems and methods that can provide a high g-force to a test specimen. An exemplary system of the present invention includes a beam, rigidly fixed at one or both ends, on which a test specimen can be mounted. A loading device is preferably provided that can load the beam by using a ceramic column positioned between the beam and the loading device. A flywheel that has a cutter that can be deployed on command while the flywheel is rotating to fracture the ceramic column is also provided. The present invention also provides systems and methods for controllably damping the oscillation of a loaded beam at some point after the load on the beam is released to produce a high g-force event. For example, a damping device of the present invention may be engaged after the completion of the high g-force event. Such damping can prevent subsequent ringing or oscillation of the beam without affecting the magnitude of the high g-force event.

摘要： Systems and methods for protecting a hardware device from shock loads in a package are disclosed. An example system includes a cover with an orifice at a first end and a closed second end, a cupped spring washer in the cover at the closed second end, a hardware package in the cover on the washer, and a base that, when attached to the cover, loads the washer and hardware package with a desired load.

摘要： A high-g shock-producing device for testing a sample specimen is described which includes a beam and a shock column. The beam is of predetermined length and has at least one end substantially rigidly fixed with the specimen mounted thereon at a position remote from the one end. The shock column is positioned to apply a force causing said beam to bend in a direction transverse to the length. The column is configured to have a buckling failure when exposed to a pressure which is sufficient to bend the beam an amount to provide the desired high-g force to the specimen. The buckling failure causes the force to be suddenly removed from the beam so as to release the beam and produce the high-g shock on the specimen.
